HONDURAS ASSURED OF U.S. COMMITMENT

President Reagan, reaffirming treaty commitments, said Tuesday that the United States would take "appropriate measures" to defend the sovereignty and territorial integrity of Honduras "against Communist aggression."

The pledge came in a joint communique issued after a White House meeting between Reagan and President Roberto Suazo Cordova of Honduras.

In issuing the statement, the two leaders cited the "close" and "cooperative" relationship of the countries as well as the "serious security threats that exist in Central America."

Administration officials said the commitment provided to Honduras was, in fact, a reaffirmation of obligations that already are found under the Inter- American Treaty of Reciprocal Assistance, known as the Rio Treaty, and the Charter of the Organization of American States.

Under the Rio Treaty, the United States and other nations that are signers say that "an armed attack by any state against an American state shall be considered as an attack against all the American states." In the OAS Charter, the use of force by members is sanctioned in the case of self-defense.

While the joint communique was designed to reiterate those points, it also sought to reassure Honduras, in strong terms, of administration resolve to assist the country in the event of aggression by its leftist neighbor, Nicaragua.
